What to do with used tea leaves

What do you do with used tea leaves? Are they good for plants ? Can I throw them in the yard around the roses? Are they deadly to plants? Just wondering if there was anything good to come from them other than the great tea:) Thanks, Sherri

Treat your Plants — Tea can be used as a fertilizer for both indoor and outdoor plants. Leftover brewed tea can be cooled and used to "water" houseplants on occasion, and infused tea leaves can be distributed in your flower garden for a nutrient boost.

Tidy Up — Because tea absorbs moisture and odors, you can place dry tea bags in shoes and other unpleasant smelling places to remove odors. Infused tea leaves can be placed in your refrigerator to help keep food odors in check.

Clean Your Mirrors — Leftover brewed tea can be cooled and used to get mirrors squeaky clean. Use a soft cloth to buff away the tea after cleaning.

I tend to keep a large, inexpensive saucepan on the stove during the winter simmering away with some cloves, cinnamon sticks, etc. I take my used tea leaves and add them to the mix. It infuses the whole house with the scent. And, it's a lot less expensive than those simmering potpourri you can buy!
